Arsenic Poisoning and the Kanchan Arsenic Filter
Tens of millions of people in Asia are affected by arsenic contaminated groundwater. A partnership between MIT and ENPHO, a Nepali environmental NGO, have invented and widely disseminated the Kanchan Arsenic Filter in Nepal. New work is taking this filter to Bangladesh and Cambodia. This video shows the successful implementation of the Kanchan with financial support from Global Water Trust.
